Pascals Triangle
Number of words: 265 | Number of pages: 1.... to science, mathematics, and religious philosophy. Pascal was born on June 19, 1623 in Clermont-Ferrand of central France. His father was a highly placed civil official and everyone expected Pascal to follow in his footsteps.
But Pascal proved to be a child prodigy. At the age of twelve, he figured out the proposition of Euclidean geometry with no help. At the age of seventeen, he wrote an essay on conic sections which contained a theorum that was named after him.
Pascal also invented many things. He constructed the first digital calculating system for his father. He invented the syringe and the hydraulic press. He als .....

Polio
Number of words: 416 | Number of pages: 2.... Use of moist heat coupled with physical therapy to stimulate the muscles was first initiated by the Australian nurse Elizabeth Kenny, and antispasmodic drugs are administered to produce muscular relaxation. In the convalescent stage, occupational therapy is used.
Disease Control
Three broad types of the virus have been identified: the Brunhilde (type 1), Lansing (type 2), and Leon (type 3) strains. Immunity to one strain does not furnish protection against the other two.
Poliomyelitis control was made possible when, in 1949, the American bacteriologist John Franklin Enders and his coworkers discovered a method of growing th .....

The Atmospheric Ozone Layer
Number of words: 2378 | Number of pages: 9.... concentrations through the depletion of UV light.
However, the need to measure ozone concentrations from the surface at regular
intervals, led to the development of the Dobson spectrophotometer in the 1960s.
The British Antarctic Survey has the responsibility to routinely monitor
stratospheric ozone levels over the Antarctic stations at Halley Bay (76°S 27°W)
and at Argentine Islands (65°S 64°W). Analysis of ozone measurements in 1984 by
a team led by John Farnam, made the startling discovery that spring values of
total ozone during the 1980-1984 period had fallen dramatically compared to the
earlier period between 1957-73. T .....

Resonance
Number of words: 524 | Number of pages: 2.... produced in the tube. This creates a pure
tone.
We can use this knowledge of one fourth wavelength to create our own
demonstration. It does not only have to be done using wind, but can also be
demonstrated using tuning forks. If the frequency of the tuning forks is known,
then v=f(wavelength) can find you the length of your air column.
Using a tuning fork of frequency 512 c/s, and the speed of sound is
332+0.6T m/s, temperature being, 22 degrees, substitute into the formula.
Calculate 1/4 wavelength
V=f(wavelength)
wavelength=V/f
=345.2 (m/s) / 512 (c/s)
=0.674 m/c .....

Drinking Water Contamination
Number of words: 4200 | Number of pages: 16.... One such study found that as many as one in three gastrointestinal illnesses — often chalked up to "stomach flu" — are caused by drinking water contaminated with microorganisms.[4]
Such microbial-related outbreaks say nothing about the many other hazards borne by our nation's water supply. Researchers have shown that millions of Americans regularly drink tap water that is contaminated with toxic and cancer-causing chemicals such as lead, trihalomethanes (THMs), arsenic, radioactive materials, and pesticides. A 1994 study estimated that some 14.1 million Americans drank water contaminated with the pesticides atrazine, cyanazin .....

Global Warming 3 -
Number of words: 2192 | Number of pages: 8.... have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century.
The warning will be the greatest at the higher latitudes of the Northern Hemisphere, with the largest temperature rises occurring in winter. Most areas will experience summertime highs well above 100 degrees Fahrenheit. New temperature records will be set each year.
As a possible prelude to global warming, the decade of the 1980’s has had the six hottest years of the century (Erandson 18-22). .....

Klinefelter Syndrome

There is really no specific frame in which it invariably happens. It is known through that it happens during the process of meiosis in which chromosomes split.
WHO IT AFFECTS???
Klinefelter Syndrome only occurs in males. This is so because females have a similar condition called Turner’s Syndrome who generally has the same side effects as Klinefelter Syndrome. Instead of having one X chrosomes they have two. Where as in Klinefelter patients are XXY, instead of XY which is the normal.

created devices and made discoveries on our behalf to make life easier for
everyone.
Before the early nineteenth century communications were inadequate. The

desperate hope for a cure, yet poison, slowly spreading in the air and along the
land. I am the colorful fireworks "sprocketed" across the dark sky when the
touch of two soft lips are gently pressed together. I am the warm tears
trickling slowly down a child's face when the thought of going to school all
alone crosses his mind. I am te pure exhilaration every time two people fall in
love. I am rubbed roughly against a filthy body and massaged along a baby's butt.
Ancient or modern, I am vigorous. .....
